Consider the network setup in Figure $4\mathrm{.}25.$ Suppose that the ISP instead assigns the router the address $24\mathrm{.}34\mathrm{.}101\mathrm{.}225$ and that the network address of the home network is $192\mathrm{.}168\mathrm{.}0/24.$ Suppose that the IP addresses, $192\mathrm{.}168\mathrm{.}1\mathrm{.}1,192\mathrm{.}168\mathrm{.}1\mathrm{.}2,192\mathrm{.}168\mathrm{.}1\mathrm{.}3,$ are assigned to three hosts, and the router interface is assigned $192\mathrm{.}168\mathrm{.}1\mathrm{.}4.$

Figure $4\mathrm{.}25$ Network address translation

Suppose each host has two ongoing TCP connections, all to port $80$ at host $128\mathrm{.}119\mathrm{.}40\mathrm{.}86.$ Assume that the host with $192\mathrm{.}168\mathrm{.}1\mathrm{.}1$ initiates two TCP connections with the WAN$-$side port numbers $4000$ and $4001$ in the NAT translation table, the host with $192\mathrm{.}168\mathrm{.}1\mathrm{.}2$ initiates two TCP connections with the WAN$-$side port numbers $4002$ and $4003$ in the NAT translation table, and the host with $192\mathrm{.}168\mathrm{.}1\mathrm{.}3$ initiates two TCP connections with the WAN$-$side port numbers $4004$ and $4005$ in the NAT translation table. The source port numbers used by each host for TCP connections are $3345,3346$ for the first host, $3445,3446$ for the second host, and $3545,3546$ for the third host. Suppose that the first host sends out the TCP SYN segment as is shown in Figure $4\mathrm{.}25($IP datagram #$1),$ Answer the following questions:

$($a$)$ What is the source IP address of IP datagram in $(2)($Enter it in the dotted$-$decimal representation$)?$

$($d$)$ What is the destination port of IP datagram in $(2)($Enter an integer$)?$

$($e$)$ What is the source IP address of IP datagram in $(4)($Enter it in the dotted$-$decimal representation$)?$

$($f$)$ What is the source port of IP datagram in $(4)($Enter an integer$)?$

$($g$)$ What is the destination IP address of IP datagram in $(4)($Enter it in the dotted$-$decimal representation$)?$

$($h$)$ What is the destination port of IP datagram in $(4)($Enter an integer$)?$
